ADS4225IRGCR

Analog To Digital Converters (ADC) Overview

The ADS4225IRGCR is a dual-channel, 14-bit and 12-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at sampling rates of up to 160 MSPS for the 12-bit mode and supports lower speeds for higher resolution. The device utilizes a pipeline architecture with differential inputs and offers LVDS or parallel CMOS digital output interfaces. It functions on a single 1.8V supply, achieving ultralow power consumption. Key performance metrics include an SNR of 70.5 dB at 12-bit/160MSPS. It is housed in a 64-pin VQFN package and operates within a temperature range of -40°C to +85°C.
